This invention is concerned with oil seals of the type disclosed in my copending application Serial No. 288,093.

e; primary object of the invention is to asdis't-inguished from floating, seal which will function efliciently and is extremely inexpensive to construct.

Other objectsand advantages will be apparent to those skilled in the art upon a full ment and operation of the seal.

One form of the invention is presented herein for the purpose ofexemplification, but it will ofcourse be understood that the invention is capable of embodiment in other forms coming equally within the scope of the appended claims. p

portions broken The seal illustrated in the drawings conapertured cup-shaped ca e 10 which is adapted to be positioned in fluidtight association with a housing 1 1, a pack.- 12 having a radially flanged ortion 13 in ttom 14 of the c e and an axially sleeved portion 15 which is adapted to be positioned in rotatable fluid-tight association with a shaft 16 passing through the same", a cu -shaped ring 17 nested within the cage with the bottom 18 .of the ring clamped against the radially packing, a washer aspun-over edge'20 of the cage in clamped engagementwith the ring, and a coil spring 21 extending under-tension about the axially sleeved portion-15 of the packing; .The pac -is made of leather or 0t er litia;iiin, a radiall n ged arrangement fe y an rtion of the'pa'eking'is' securely clam tween the bottom of the cage and the ttim'of the ring throughout'jsubetantially its entire radial extent. 7

The packing is prevented from rotating? the construction, arrangethe cage,

the radially extendm of the ring, the rim of the cage and the rim of the n testimony whereof I have hereunto su g by reason of the simple with the shaft by means of spur-like projections 22 on'the bottom of the spacing ring, which projections are embedded in the opposed face of the packing. The ring is preventing from turning with respect to the washer by means of a tongue 23 on the washer which is deflected laterally into a notch 24 in the rim of the ring,- and the washer vented from turning with by an indention 25 in the spun-over edge of the cage at the location of the recess formed by the deflection of thetongue 23.
